Faced with the global strategic goals of sustainable development and the intensified the contradiction between people, the implementation of land consolidation activities are undoubtedly an effective way to achieve sustainable use of land resources, to ease the contradiction between people, to improve the living environment and ecological environment. In recent years, with the advance of large-scale land consolidation activities, in advance to arrange a way to increase arable land area of agricultural land quality, especially the quality the of arable land will become the future to ensure food security in China’s important measures. Base on this, it has important practical significance for Suitability Evaluation Land Consolidation.In the Arable land suitability evaluation, constructing the evaluation system is one of the key elements of the comprehensive evaluation index system.But there has not yet formed the method of standard and universal screening index. The existence of one-sided index system, the irrational structure, indicators redundancy and other issues affect the authenticity of the land evaluation results.Weights status of land evaluation is particularly important, whether it constitutes a reasonable direct impact on the comprehensive evaluation system. As a result, each index determined with respect to the right of the total index weight is often a matter of debate. Based on this, the introduction of the principle of set theory attribute reduction and attribute importance to build rough principle of arable land consolidation suitability evaluation index system for the calculation of the weight of arable land consolidation and the right to choose suitability assessment provides a new approach. By building on rough set theory and fuzzy comprehensive evaluation of cultivated land consolidation suitability evaluation model, complementary advantages, and further improve scientific and rational evaluation system and enhance the operability and reliability of the evaluation to improve the efficiency of the evaluation, the Arable Land Consolidation Suitability Evaluation provides a new means and ways.Finally, the paper takes HuXian country for an example, focusing on farmland land consolidation, considering the natural, social and economic factors of Huxian farmland, using arable land suitability assessment model for assessing consolidation area of cultivated land consolidation suitability level, division level area.The paper consider the arable land suitable consolidation area of HuXian country is concentrated in GanTing village, CangYou village, QinDu village, YuXia village, WuZHu village and other towns. And in southern of LaoDian and Wei Feng village, there is a small amount of the distribution. For the area of future grid fields consolidation, fertility and other project-based land management work, improve the layout grid fields, thus increasing the effective arable land, improve soil fertility and improve the quality of cultivated land. Finishing inappropriate concentrated in Dawang, northern and northern Wei Feng, the town of Ishii small amount of distribution.
